NUT-LOCK.

Specification of Letters Patent.

Patented Deo. 24:, 1907.

Application led May 24:. 1907. Serial No. 375,533.

To all whom it may concern:

Be it known that I, ALFRED K. SPINNEY, a citizen of the United States,residing at Toledo, in the county of Lucas and State of Ohio, haveinvented new and useful Improvements in Nut-Locks, of which thefollowing is a speciication.

This invention relates to nut locks designed for use in connection withrail joints, although they are not necessarily limited to this use. j

The invention has for one of its objects to provide a comparativelyTsimple and inexpensive nut lock comprising a spring nut coper- 'atingwith a washer which is held from rotating on the bolt as the nut isdrawn up.

A further obj ect of the invention is the provision of a nut lockespecially intended for rail joints in which one of the fish plates ofthe latter is provided with non-circular countersunlr openings for thebolts, the countersunk portions serving to receive correspondinglyshaped projections on the washers of the nut locks.

With these objects in view and others, as will appear as the descriptionproceeds, the invention comprises the various novel features ofconstruction and arrangement of parts which will be more. fullydescribed hereinafter and set forth with particularity in the claimsappended hereto.

In the accompanying drawing, which illustrates one of the embodiments ofthe invention, Figure l is a transverse section of a rail joint providedwith the improved nut locks. Fig. 2 is a fragmentary sectional view ofthe members of one of the nut-locks. Fig. 3 is a perspective view of thewasher. Fig. 4 is a similar view of the nut.

Similar reference characters are employed to designate correspondingparts throughout the several views.

Referring to the drawing, 1 designates a rail for railroads of standardconstruction,.

and 2, the fish plate for joining two adjacent rail sections together.These fish plates are of ordinary form except that the bolt-receivingopenings 3 of one of the plates are councountersunk openings 4 serve toreceive correspondingly shaped projections 5 on the washers 6 of the nutlocks.

The washers are assembled freely over the bolts 7 that pass through theopenings 3 and 8 of the fish plates and rails in the usual manner. Theouter surfaces of the washers are concaved as indicated at 9 and thenuts 10 on the bolts 7 are provided with concaved faces ll presented tothe concaved faces of the washers. By concaving the membersin thismanner, the nuts 10 can be drawn tightly up against the washers and heldunder tension.

In practice, two rail sections are placed together and the iish platespositioned thereon in the usual manner and the parts secured together bythe desired number of bolts 7. After the bolts are inserted through theopenings 3 and 8, the washers 6 are placed on the bolts in such a mannerthat the projections 5 will en ter the countersunk portions of theadjacent flsh plate. After this is done, the nuts 10 are screwed on andtightly drawn up against the washers so as to be held under tension. Anut lock of this character serves effectively to hold the parts of therail joint together and the cost of construction is comparatively small.

From the foregoing description, taken in connection with theaccompanying drawing, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains, and while vI have described theprinciple of operation of the invention, together with the device whichI now consider to be the best embodiment thereof, I desire to have itunderstood that the device shown is merely illustrative and that suchchanges may be made when desired, as are within thel scope of theclaims.

Having thus described the invention, what I claim is 1.
